The address where I sent my ECU was PowerChip, 2209 Federal Ave., Los Angeles, CA. Maybe they have upgraded since then. I used PowerChip because I heard many good things about them on this and other forums. They are also what is to be believed a "reputable" company. The alternative was Upsolute but after researching, it seemed like a coin toss.

I am hoping things went well today and should have some new information to post tomorrow.

Also thanks for the Auto Zone tip...we have discussed it.
